The rare earth element (REE) tetrad effect includes a large, strongly negative Eu anomaly, and appears in highly evolved, fractionated granite and/or A-type granite, which it is sometimes interpreted as evidence of fluid-rock interaction. Magnesium i

The Northwest Africa 5738 eucrite contains a record of unprecedented geochemical complexity for a sample from the HED asteroid. It originated with a uniquely evolved (Stannern Trend) primary igneous composition, combining ultra-high bulk incompatible

RATIONALE Cryogenic trapping using molecular sieves is commonly used to collect O2 extracted from silicates for 17O/16O and 18O/16O analyses. However, gases which interfere with 17O/16O analysis, notably NF3, are also trapped and their removal is ess

Northwest Africa 6693 is a new type of achondrite, with a unique combination of oxygen-isotopic composition (low Δ17O: −1.08‰; also δ17O = 1.19‰) and FeO-rich, low mg bulk composition. A mode (in vol%) shows 70% pyroxene, 16% olivine and 13%
